7 days from MS  impressive.
I went from spore to harvest in 21 =) I'll never not incubate, don't know why people aren't.
So I picked up a few things to get my incubator set up again (my last aqua heater took a crap) and I figured I would share.
I know, half of you are going to say that incubation is outdated, that it increases contam risk, etc.
Well, too bad. 
I keep my temps around 80 for my grain masters, which I find to be perfect and speeds colonization up significantly.
There is no added contam risk to properly prepared and sterilized jars. Endospores that survive the PC cycle take a long time to recover and at 80F, your jars should colonize within 5-14 days, depending on type of inoculation and how much you like to shake the jars while they colonize.
And if you have any live mold spores or bacteria in that jar that you think your myc will "outrun" at lower temperatures, then you've already lost the battle.
The design is pretty much just Magash's TiT incubator.
I use two 35gallon opaque plastic tubs, a 50w aquarium heater, 4 tall half-pint jars, and an air stone and air pump. Total cost for me to buy locally was about $50 US.
I put the heater on the bottom of the first tub along with the air stone for more even distribution of heat, which i've found to be very important.
  
The heater is set at 80F.
The second tub sits inside the first. I used tall half-pint jars (submerged) to keep the tub from resting directly on the heater.
I used zip-ties to strap the second tub down to the first. It will definitely try to float if you do not.
Then I fill the water level about halfway up the sides of the second tub. I also add about 1/4 gallon of bleach to every 5 gallons of water or so.
And that's all there is to it 
Optionally you can add a wire shelf cut to fit for an extra bit of space 
Here it is (obviously the lid is on when it's not being messed with, I was just lazy with pictures):
This keeps temps in my cold basement and in my fruiting room as well.
I urge the skeptics to at least give incubation at proper temperatures a chance, you will be surprised at the result

its more so to beginners in growing mushroom that we try and stear them away from incubators.
But if you have experience and have your incubator dialed in, theres no reason why they wont get thigns done quicker.
Its better for a spomeone beginning to just be patient and wait the little extra time, rather than having things go wrong and get discouraged.

I hear that.
It's just that most people never get out of that misconception, so hopefully this will help folks be less scared of a little warmth

Me too 
I just use it for my grain masters and petri dishes. Cuts the colonizing time almost in half. And I can fit almost 60 jars in that TiT.
I usually have around 200 spawn jars that get g2g'd into for whatever species I'm working on, they colonize so quick i just keep em at 74F in my grow room

I can confirm FH
My jars took over 4 weeks when the temps were at around 65F
Since I wrapped them in a heating blanket - they take about 10 days
at 80F...

I just bought a tit incubator and after I got it I heard a bunch of people say that it was a bag idea and I would be better off to colonize in room temp. I can say that after 2 weeks of using the tit, It seams to work good for me. I leave the cover off and it stays a consistent 76-78 degrees. it also puts my humidity and temp in my martha up without running a separate heater or humidifier, works good!! I did have to clean the water once but it only took about 10 min, no big deal

so, i know fruiting at higher temps results in (ime) hollow stipes, which always pissed me off. when you colonize at higher temps, is there an impact on fruiting? what temps do you generally fruit at?
might be a dumb question, but its mine.

Nice work again Frank.
Whilst the air-pump usage may seem obvious to most I think as this is a ‘TEK’ then perhaps the reasoning, placement & rough cost of the air pump should be included?

This.
This is why incubators were looked down upon. Many newbies struggle with proper sterilization as is.
If you are not new, or can afford a good heater(Pro heat serious works awesome) then incubate.
Frank. Now that you have these set up. Could you do a test for me that I never got around to doing.
One big tub for your heater. Place two smaller tubs inside. One clear, one not. Use an isolate. Use small 1/2 pint jars. Don't shake to avoid and chance of randomization. I got money on the dark tub.

Mine is a pair of sterilite tubs (The water one is 24qt, and the other is slightly shorter in height...maby 16 qt) inside a larger 72 qt grey tub. The aquarium heater is inside the clear 24 qt. I use a 5-10 gallon rated heater that is automatically set at 78-80 degrees. It don't hold alot of quart jars, but it does make a huge difference in colonization times. I have not been concerned with what nay-sayers have said about TiTs. I love TiTs. I love tits too.

Thats good. I don't use an air stone in my TiT either. Heating a room is always better than heating a tub of fluid in most cases. I however CANNOT due to limitations of the design of my home get my office up over 70 this time of year. Id love to have a space that I can jack up to the high 70s....but at this time of year, Id love to have a space I can jack up to the low 70s lol.

yeah I wish I could heat entire rooms as well. This chills in my walk in closet on low heat. The growth has sky rocketed. I understand everyone has their own situation but if u have thirty dollars to spare and the right situation for it I highly recommend it.

I have two
I'm always recommending them to people.
But I can't keep my fruiting room at 80F and expect my tubs to stay at a decent temp while they colonize. Since I colonize and fruit in the same room, the incubator is perfect.
Citric, I will give that a shot when I have some room in there, it's a little full right now!
Also, regarding the air stone, I found when I first started using this that if I didn't have something circulating the water, the heater itself would make the bottom of the second tub (and the bottom of the jars inside) too hot.
Magash said its optional but I wouldn't go without.

Yeah I may give it another shot when I get some funds for an airstone. petsmart let me return the heater after like 20 days. That was prime. There would be some areas of the tub really warm and some as if it wasnt even in the incubator.

Yeah, my first time running it I remember I lost a few jars because they got so hot above the heater. Circulating the water prevents that.
It also makes a very silly "BLOOP!" sound every couple of minutes when a big air bubble comes to the surface

Nice pictorial, Frank, as always.
Do you ever have problems with stuff growing in the water? How often do you change/clean it? Have you ever tried adding bleach, or maybe some of that humidifier anti-bacteria/anti-algae water treatment?
I was at one point considering building a TiT using mineral oil instead of water. That's what is used for things like giant electrical transformers. It wouldn't grow contaminants and it wouldn't evaporate. I guess circulating might prove to be challenging, though, since an airstone might not work quite so well. Maybe some kind of little electric oil pump...

I change the water between cycles of master jars, usually once a month or so. I add about 1/3 of a bottle of H2O2 to the water and the air stone keeps it from getting stagnant.
I updated the OP with this info and a bit more
I don't know why you would want to mess with mineral oil. That sounds incredibly messy and to fill my tub up to the needed level, I'd have to use about 14 gallons of oil

I've noticed way faster growth on my petris and also the jars i have in there. Luckily I had an aquarium heater from when i first started growing. Took 5 minutes to set up. Cant believe I needed this reminder to set it up again, but thanks.
I used extra pint jars for the separator between tubs

I see your points about the oil. My thought about it was just that it could essentially be maintenance-free. But, yeah, it'd be messy for sure. And expensive.
The peroxide is a good idea.

I realized this could use an extra level for petris or half-pints, so I cut a piece of wire shelf to fit inside perfectly. Added a pic to the OP as well

I just started out with a TIT. No airstone, just aqua heater. I didn't want to zip tie it because it seems like it would be a pain to cut the ties when your first getting the temp right on the heater.
First off I set it to 28 and it didn't seem to be getting warm enough inside, possibly because it was floating so I turned it up and i think it was too hot, started getting a lot of contams and condensation.
Next up I tried the water stone and pump as suggested but there were two problems. One, the bubbling gurgling noise is pretty loud if its in your room. Two, it somehow messed with the heat sensor in the aqua heater and it stopped heating, as if warm bubbles were hitting it and signalling a higher temp. Sounds strange but that's what seemed to be happening.
I turned the pump off, turned the temp down and put some weights on top and it seems to be better now but one side of the bottom tub is still going to be warmer.
First time I put some plates in I also put the left over baby bottle of agar in that I had noccd. I checked it a day later and the agar had moved in the bottle and re-set on an angle. Now I raise the plates above the jars/ LC by putting a scrunched up survival/ heat blanket (disposable silver thing) as a buffer in between and to raise the plates. Cant fit a fridge shelf.
I want to get a consistent temp across the bottom. Maybe I should put the heater up one end and the stone up the other and see if that stops it from interfering with the sensor? I just dont want to zip tie it because it seems like I might be cutting them all the time in the process of working this out.

get a reptile thermostat to run with your aquarium heater. or just let your jars colonize at room temp either or

Nice write up. To anyone having bacterial issues, try a grain other than rye. I see issues (bacterial) exclusively from rye sometimes.
I too, go against all recommendations and keep jars warm.
The oil filled radiator in a closet setup is a blessing for the hundreds of jars setup...
The basement is just too cold in winter.

Wow. Just wow.
Inoculated five PF jars with blue oyster culture last night.
Visible mycelium growth in at least one inoculation point of every jar after only 24 hours. Tub is holding consistent temperature of 83 degrees F.
Consistent temperature really does the trick. I will never go back. Ever. Thank you so much frank.

At least it's better than the kind of heating mats some people use (basically heater blankets, there's an infared kind sold by azarius but I'm not sure if that's any better). My first time, I had a heater pad on a timer (only 30 mins at a time, once every 2 hrs on low, with towels I'm between) and at one point, the temp inside the incubator box (basically a glove box) shot up to 92 degrees. Luckily this was for only twenty minutes, and this was colonized at around 78-80 degrees, I then tried not incubating (70 - 75) and got a higher yield and even faster colonization. Go figure.
Only difference was one was cambo one was B+, both fast colonizers. Heat does seem to increase yield per flush per cake (it SEEMED) but overall less flushes. Of course this could be just the genetics as well
Btw also people say not to use digi hygrometers in the FC but I did and it worked just fine. It was a brand that came with a friends grow box (which was an essentially useless PMP but had some cool parts and really good substrate, it was simply filled with holes and became a shotgun)

Jars/bags/tubs/trays should colonize @ room temperature getting ambient/indirect light.
Main pinning triggers are full colonization, FAE and Evaporation off of the substrate.
Light is a secondary pinning trigger. For tropical species temperature is not a pinning factor.
P. Cubensis are a tropical species. You could colonize at 70F and fruit at 80F with great results.
Light has been proven beneficial during all stages of mycellium growth. Mushrooms like mammals have a circadian rhythm.
You want ambient/indirect light(on a 12/12 schedule preferably) for colonization and consolidation.
You want direct/intense 6500K light on a 12/12 schedule for fruiting.
Optimal temps are mid 70s throughout the whole grow, but anywhere from 65F-80F is acceptable.
Incubation is outdated/uneeded unless temps in the range stated above cannot be kept.
The inside of the jar is always a few degrees warmer than the outside because the mycellium produces heat..mycellium tends to stall at temps above 86F , and contams thrive.
Fruiting at cooler temps tends to produce denser, meatier fruits, while fruiting at higher temps will often produce hollow, less dense stems.

New grower here, I made this incubator and is there any way to stop the "bloop" from happening?
Nope, if you can figure out a way while retaining the water circulation, I'd definitely give it a shot.
Hey pussyfart, did you post that on the wrong thread? Not seeing the relevance here

think pussyfart just wanted to point this out so th OP does not think this is to warm above room temp and that it is not needed if this is easily acheivable. When in colder places(less than 70 F) then incubators are key

I read up on TiT's a few weeks back and someone made mention that the aquarium heaters don't always keep a stable temperature, maybe swinging a few degrees here and there.
Can anyone comment on this phenomenon? Is this an issue anyone has run into?
The solution to the problem was to get a 2 liter plastic bottle, fill with sand and then insert the aqua heater into the bottle. The sand was a buffer for heat swings.

I don't get heat swings because there is constant flow in the water, provided by the bubbles being trapped under the inner tub and splashing to the surface a couple times a minute
No need to over-complicate it. I've been running mine for a year now, I won't ever go without it

Is the temp in the corners the same as the temp in the center of the tub? Does the upper "shelf" get hotter than the lower layer of jars?

Not more than a degree or two. Certainly nothing to worry about. The water sits @ 80F and the inner tub sits at 78F.
You should quit thinking about it and try it, the benefits are pretty nice if you live in a cool climate

Well my place hovers between 68-72 so I decided I wanted to keep a steady temp for my grains to colonize @. I've already been following your "12 steps to getting shit done" page (plus reading the more in depth links that you have for getting shit done . So I decided I might as well get a TiT too. I used transparent 66qt tubs though. I did this because PussyFart's post.. and I quote....
"Light has been proven beneficial during all stages of mycellium growth. Mushrooms like mammals have a circadian rhythm.
You want ambient/indirect light(on a 12/12 schedule preferably) for colonization and consolidation."
So I decided to keep it transparent and I can also see if the water get's an nastiness in it. Any thoughts?

I have an incubator with a LTL digital heating temp controller hooked to a space heater set at 78F and it wont go past 79 and by house is never over 70F so idt i will have a problem unless the space heater dries out the substrate!
I am following your 12 step guide right now have grain drying after the 5 minutes med-high boil!

How much more beneficial is the air stone, compared to just the air pump?

Frank,
In your earlier post, you expressed an interest in a better way to circulate the water in the bottom tub.
I have a suggestion, but haven't tried it, but thought I'd share.
I remember from the old days when we needed circulation in the lab, there were "Magnetic Stir Plates". You could put a stir plate under your tub and drop a magnetic stir rod in the tub, and it would circulate the water... without the "bloop."
I did an intial search for magnetic stir plates and found that they are expensive new. Perhaps they are available on eBay or Craig's List? Here is an example: http://www.amazon.com/SocalHomeBrew-Magnetic-Stir-Plate/dp/B008F0CTBA/ref=sr_1_22?s=industrial&ie=UTF8&qid=1421111497&sr=1-22&keywords=magnetic+stir+plate
Your solution is undoubtedly less expensive, but in the event someone has this equipment lying around... go at it.

How can you use this technique with the BRF Tek fc as you have to drill holes all over the tote box?

You cannot. This is for an incubation chamber not a fruiting chamber. If you need higher fruiting temperatures you'll need to heat the room.

Quick question...
I had two of these running my last run without airstones and got some nastiness in the water...just smells moldy. Does the airstone prevent this from happening, and if not are there any additives that can be put in the water to keep it clean?

unless your house is colder than 65F you don't need to incubate at all anyway. and if your place is cooler than 65F regularly just get radiator type space heater or turn your heat on.
air stones wont prevent nastyness they'll encourage some kinds by increasing dissolved oxygen. change the water daily

Switching water is what I was trying to avoid...I could rig up a fill/drain tube like people use for bubble buckets, but fuck that's a lot of work.
The reason I'm thinking about TiTs is cause I'm planning to move my SAB, fridge, ect to the basement and just letting spawn colonize there. Temps are probably in the 60s now but not sure how cold it gets down there in the winter.
I could probably save up enough for a heater between now and then, if I budget good.

Its funny i was using all of Frank's teks for a long time, and worked very well (Thank you, good sir!)
But i was taught that apparently now no one pasteurizes their coir. I tried it the way they described, using boiling water to hydrate the mixed up CVG. So far, perfectly good colonization, i think one tub has even beautifully finished its spawn run. Assuming i dont get contams (usually even after 3rd flush is still fine), this method is actually easier. That said, "how frank gets shit done" is a Huge part of my mushy education.
As for incubating, you never need to do it. You just keep everything above 65 degrees. Theyre basically comfy at the same temps you are. Cold at the same temps and hot at the same temps
Just like pasteurization, i have incubated before, and sure you *can*, but in the summer? Usually if its done its when the weather might be too cold for the jars. If youre in the 70s or even upper 60s, you are good. Really even 60 degrees isnt the end of the world, though you wouldnt wanna go much further. But same with 86 degrees or hotter.

I just discovered this thread hunting for an incubator or something to speed up growth. I keep my apartment at an ambient 70F. I did not realize until I planted marijuana seeds that the soil temperature was almost 10F lower. It made me wonder the temperature on my plates (after 10 days I had growth. Grateful as hell, but slow, very very slow).
Incubators are pretty expensive. I saw this tek and want to give it a shot. Can I put my plates in it for growth or should I just be happy with what I have? Ultimately I'm planning for a monotub (following Bod's teks). I'm also moving in 6 months so idk if I'll have enough time by then without an incubator.
Sorry to bump up such an old topic. Thank you guys all for all of the information!!
